Objective To analyze the diagnostic value of shear wave elastography (SWE) combined with vascular endothelial growth factor B (VEGF-B) and hemoglobin A1c (HbA1c) in early diabetic peripheral neuropathy (DPN). Methods A total of 100 patients with type 2 diabetes mellitus (T2DM) admitted to Mianyang Central Hospital between October 2020 and October 2023 were selected and divided into a T2DM with DPN group (n=31) and a T2DM without DPN group (n=69) based on the presence or absence of DPN. Additionally, 50 healthy individuals from the same hospital’s health examination center were included as a healthy control group. The basic clinical characteristics, mean elasticity (Emean) values of the left and right median and tibial nerves, serum VEGF-B, and HbA1c levels were compared among the three groups. The diagnostic efficacy of SWE, VEGF-B, and HbA1c for DPN was evaluated using receiver operating characteristic (ROC) curves, and Pearson correlation analysis was performed to assess the relationships between median/tibial nerve Emean and VEGF-B/HbA1c. Results The Emean values of the left and right median nerves, Emean values of the left and right tibial nerves, serum VEGF-B, and HbA1c levels in the T2DM with DPN group were significantly higher than those in the T2DM without DPN group and the healthy control group (P<0.05). The Emean values of the left and right median and tibial nerves, Emean values of the left and right tibial nerves, and HbA1c level in the T2DM without DPN group were significantly higher than those in the healthy control group (P<0.05), while no significant difference was observed in serum VEGF-B level between the T2DM without DPN group and the healthy control group (P>0.05). The area under the ROC curve for the combined diagnosis of DPN using SWE, VEGF-B, and HbA1c was 0.859 [95% confidence interval (0.828, 0.955)]. The sensitivity of the combined diagnosis (93.72%) was significantly higher than that of individual diagnoses (78.82%, 75.39%, and 71.05%, respectively; P<0.05), while the specificity (88.64%) showed no significant difference compared to individual diagnoses (80.18%, 78.96%, and 82.88%, respectively; P>0.05). Positive correlations were observed between median/tibial nerve Emean and VEGF-B/HbA1c levels (r=0.428, 0.395, 0.416, and 0.416, respectively; P<0.05). Conclusions Elevated median/tibial nerve Emean, serum VEGF-B, and HbA1c levels are closely associated with DPN. The combination of SWE, VEGF-B, and HbA1c improves diagnostic sensitivity for DPN, demonstrating significant clinical value.
Objective To study relationship between hemoglobin-AGE (Hb-AGE) levels and diabetic retinopathy (DR) in diabetics. Methods Hb-AGE content of 125 type 2 diabetic patients with or without DR was measured by competitive ELISA technique and compared with that of 50 normal controls. Results Hb-AGE level in type 2 diabetic patients was 65% higher than that in normal individuals (Plt;0.01), and Hb-AGE level in the patients with DR was significantly higher than patients with DR was significantly higher than that in those without DR (Plt;0.05). It was found that fasting plasma glucose (FPG) level was not directly correlated with Bb-AGE levels and development of DR ,but HbAc,plasma lipid and blood pressure were related to the both (Plt;0.05 or Plt;0.01). Multivariate analysis showed that there was closer relationship between seriousness degree of DR and Hb-AGE (partial correlation coefficient was 0.604,Plt;0.001). Conclusion Diabetic control is related to alterations in vivo Hb-AGE,which may contribute to occurrence and developement of DR in type 2 diabetes mellitus. (Chin J Ocul Fundus Dis,2000,16:147-149)

ObjectiveTo explore the association between glycosylated hemoglobin level and poor prognosis in acute ischemic stroke (AIS) patients treated with intravenous thrombolysis.MethodsThe AIS patients treated with recombinant tissue-type plasminogen activator who were hospitalized in the Department of Neurology of the First Affiliated Hospital of Henan University of Science and Technology from September to December 2020 were retrospectively included. According to different levels of glycosylated hemoglobin, they were divided into pre-diabetic group (5.7%≤glycated hemoglobin≤6.4%), diabetic group (previously diabetic or glycosylated hemoglobin≥6.5%), and non-diabetic group (glycated hemoglobin <5.7%). The relevant information of the patients was collected, and a telephone follow-up was conducted 90 days after discharge. According to the modified Rankin Scale (mRS) score, the patients were divided into the good prognosis group (mRS score≤2) and the poor prognosis group (mRS score>2). Logistic regression analysis was used to determine the risk factors for the poor prognosis of intravenous thrombolysis in patients with AIS.ResultEventually 101 patients were included, including 44 in the non-diabetic group, 24 in the pre-diabetic group, and 33 in the diabetic group. And 64 patients were in the good prognosis group and 37 patients were in the poor prognosis group. Regression analysis results showed that diabetes was associated with poor prognosis 3 months after intravenous thrombolysis in patients with AIS [odds ratio=6.518, 95% confidence interval (1.568, 27.096), P=0.010]; and the higher the National Institutesof Health Stroke Scale score at admission was, the higher the risk of poor prognosis would be [odds ratio=1.421, 95% confidence interval (1.231, 1.640), P<0.001].ConclusionIn AIS patients who received intravenous thrombolysis, diabetes is associated with poor prognosis after 3 months.
Objectives To systematically analyze the effect of high-intensity and low-intensity resistance training on glycosylated hemoglobin (HbA1c) in elderly patients with type 2 diabetes. Methods PubMed, EBSCO, Cochrane Library, Web of science, Wanfang, Chinese National Knowledge Infrastructure and Chongqing VIP were searched to collect randomized controlled trials of resistance training intervention in elderly patients with type 2 diabetes. The search time limit was from the establishment of the database to August 28, 2021, and the RevMan 5.3 and Stata 15.0 software were used for meta-analysis. Results A total of 415 patients in 8 articles were included in this study. A subgroup analysis based on control measures showed that compared with the resistance training group, the HbA1c level effect value of the non- training group was weighted mean difference (WMD) = −0.54% [95% confidence interval (CI) (−1.06%, −0.03%), P=0.04)], the HbA1c level effect value of the flexibility training group was WMD=−0.47% [95%CI (−1.05%, 0.12%), P=0.12], the HbA1c level effect value of the aerobic training group was WMD=−0.10% [95%CI (−0.71%, 0.51%), P=0.75]. Subgroup analysis of resistance strength showed that compared with the flexibility or non-resistance training group, both high-intensity [WMD=−0.99%, 95%CI (−1.16%, −0.81%), P<0.00001] and low- and medium-intensity resistance training [WMD=−0.29%, 95%CI (−0.58%, −0.01%), P=0.05] can reduce HbA1c. Compared with the high-intensity resistance training, the HbA1c level effect value of the low- and medium-intensity resistance training was WMD=0.03% [95%CI (−0.33%, 0.39%), P=0.88]. Compared with the low- and medium-intensity resistance training, the HbA1c level effect value of the low- and medium-intensity aerobic training was WMD=−0.10% [95%CI (−0.71%, 0.51%), P=0.75]. Among all the included studies, only the high-intensity resistance training group reported multiple adverse events.ConclusionsCurrent evidence suggests that elderly patients with type 2 diabetes are more suitable to choose low-to-medium-intensity resistance training to control HbA1c. It is recommended that elderly patients with type 2 diabetes take 60% to 75% of the maximum muscle strength of medium-intensity resistance training.
ObjectiveTo study the relationship between preoperative pan-immune-inflammation value (PIV), preoperative hemoglobin, albumin, lymphocyte and platelet score (HALP) and tumor pathological features and microsatellite status of colorectal cancer, and to analyze the predictive value of HALP and PIV for microsatellite status. MethodsThe clinicopathological data of 156 patients who underwent radical colorectal cancer resection admitted to the Second Hospital of Shanxi Medical University from May 2021 to February 2024 were retrospectively analyzed. HALP and PIV were calculated by preoperative related laboratory indicators, and then the patients were divided into high HALP/low HALP (HHALP/LHALP) group (n=78) and high PIV/low PIV (HPIV/LPIV) group (n=78) according to the median of their calculated values. The correlation between preoperative HALP and PIV and clinicopathologic features of colorectal cancer was analyzed. According to the results of microsatellite stability detection, the patients were divided into microsatellite standard/microsatellite instability-high（MSS/MSI-H）group. The correlation between preoperative HALP and PIV and microsatellite stability was analyzed. The predictive value of HALP and PIV for microsatellite status was analyzed by using receiver operating characteristic (ROC) curve. ResultsThere were statistically significant differences in tumor diameter, tumor location, HALP, T stage and microsatellite status between the HPIV group and the LPIV group (P<0.05), and high PIV was more common in patients with right-sided colon cancer and MSI-H, and the tumors were larger and had higher T stage. The differences in gender, body mass index（BMI）, tumor diameter, tumor location, PIV, T stage and microsatellite status between the HHALP group and the LHALP group were statistically significant (P<0.05), and low HALP was more common in women, patients with right-sided colon cancer, and MSI-H, and had a low BMI, large tumors, and high T stage. There were statistically significant differences in HALP and PIV between MSS group and MSI-H group (P<0.05), and patients with MSI-H tended to have low HALP and high PIV, and the area under curve of HALP and PIV in predicting MSI-H for colorectal cancer was 0.848 9 and 0.851 6, respectively, and the optimal cut-off value was 26.84 scores and 507.04, respectively, and the sensitivity was 1.000, 0.923, specificity 0.643, 0.817, respectively. ConclusionLow HALP and high PIV are more common in patients with right-sided colon cancer and MSI-H, who have poor nutritional and immune status, severe inflammation, larger tumors, deeper invasion, and predictive value for MSI-H, which can assist in the formulation of clinical treatment plans to a certain extent.
